SOC ANALYST

When you care about speed, certainty, and not chasing ghosts, Stairwell helps SOC analysts answer questions like:

  • Is this file malicious, suspicious, or benign in our environment?
  • What does this file actually do at a code level?
  • Is this a known malware family, a variant of something we know, or something new to us?
  • Is this just a repackaged or re-signed version of an existing threat we already understand?
  • Is this file rare in our environment or common and expected?
  • Have we ever seen this file anywhere in the environment before?
  • On which hosts has this file appeared?
  • When was the first and last time this file appeared in the environment?
  • Did this file show up weeks or months before it was known to be malicious?
  • What variants of this file have ever been seen, and where did they run?
  • Has this threat already come through a different delivery path or loader in the past?
  • Can I trust this alert, or is it likely noise based on historical behavior?
  • How should I prioritize this alert compared to everything else in my queue?
  • Does this file connect to suspicious infrastructure such as rare domains, IPs, or certificates?
  • Are there payloads, droppers, or loaders that I should be looking for?
  • Have we already triaged an identical or similar sample, and what decision did we make?
  • Does this sample overlap with other alerts in the environment and group them into one incident?
  • On which endpoints do I need to remove this file to consider it contained?
  • After I quarantine or delete it, can I prove it is gone everywhere it existed?
  • Can I safely close this alert with high confidence that I am not missing a variant?

INCIDENT RESPONSE TEAMS

When you care about scope, containment, and proof, Stairwell helps incident responders answer questions like:

  • When did this threat first appear in our environment, and on which host?
  • Which endpoint is true patient zero for this incident?
  • How many hosts ever saw this file?
  • Which users, processes, or applications introduced this file into the environment?
  • Did this binary or any of its variants appear on domain controllers or critical servers?
  • Did we see different stages of the same malware family across endpoints, such as loaders, droppers, and payloads?
  • Are there related tools such as credential harvesters, web shells, or tunneling utilities associated with this campaign?
  • Did this threat reuse tooling or infrastructure from prior incidents we handled?
  • On which systems does this malware or any of its variants still exist right now?
  • After containment actions, did any endpoint later reacquire or re-execute the same malware?
  • Can I show that all known variants of this malware family have been removed from the environment?
  • Can I provide time bound evidence that no hosts currently contain the file or its variants?
  • Can I answer an executive or regulator who asks, "Are we sure it is fully contained"?
  • What is the full execution chain from initial file to final payload and infrastructure?
  • Are there new variants of this threat that did not trigger our original detections?
  • Are we impacted by a newly public malware family seen in our historical data?

THREAT INTELLIGENCE TEAMS

When you care about lineage, reuse, and operating ahead of public intel, Stairwell helps threat intel teams answer questions like:

  • Which malware family does this sample belong to based on code, not just labels?
  • What are all the known variants of this family in our environment across time?
  • Are we seeing the same toolset repacked and redeployed in multiple campaigns?
  • Which domains and IPs are associated with this sample and its variants?
  • Do any of these indicators overlap with known clusters, actors, or campaigns we track?
  • Are we seeing staging servers, C2 infrastructure, or download URLs that were used before in other operations?
  • Can we pivot from one sample to all related infrastructure and second stage payloads?
  • Can we map loader to payload to infrastructure across incidents and time windows?
  • Which YARA rules match this sample now, and which would have matched it in the past?
  • Can I see every historical sample that a new rule would have flagged, across all time in our environment?
  • Which rare or suspicious binaries in our environment look like emerging threats but are not yet in public feeds?
  • Where else in our environment do we see code, or strings that rhyme with this sample?
  • How quickly can I turn new intel or reports into concrete detection coverage in our own corpus?
  • Are we seeing threats in our environment before they show up in public services or feeds?
  • Do we have an internal, private malware corpus that is as rich as what we send to third parties?
  • Are our internal intel reports backed by complete historical evidence rather than snapshots?

CISOs

When you care about risk, visibility, and credible answers to hard questions, Stairwell helps CISOs answer questions like:

  • Do we have true hindsight across our environment, or only point in time snapshots?
  • Can we answer "have we ever seen this malware or variant" in seconds, not days?
  • Are we relying on public VirusTotal style systems that expose our uploads and intellectual property?
  • Is our threat intelligence something we own or something we rent from vendors?
  • Are we blind to malware that predated our current tools and controls?
  • Are my SOC and IR teams spending their time investigating or just chasing noise?
  • How long does it take us to go from alert to understanding and confident decision?
  • Are we able to operationalize new threat intel instantly, or are we constantly playing catch up?
  • Where are our biggest malware hygiene gaps in terms of high risk binaries and weak coverage?
  • Are we uploading sensitive binaries such as in house software or proprietary tools to public services?
  • Can I show that we have private, encrypted visibility rather than crowdsourced exposure?
  • Are we at risk of adversaries seeing what we upload and adapting to our detections?
  • When a new campaign hits the news, can I quickly answer "have we ever been impacted" with evidence?
  • Can I prove incident containment with specific facts rather than cautious language?
  • Can I quantify the reduction in dwell time and time to clarity we gain from continuous hindsight?
  • Can I show auditors and regulators a clear record of what ran where and when?
  • Is our spend on threat intel aligned with outcomes, or simply buying feeds we cannot fully use?

IT AND ENDPOINT MANAGEMENT TEAMS

When you care about inventory, hygiene, and keeping unauthorized software out, Stairwell helps IT and endpoint teams answer questions like:

  • What executables and scripts are present on each endpoint right now?
  • Which binaries are newly introduced in the environment over the last day, week, or month?
  • Which machines are running software that is not on the approved list?
  • Where are unsigned or rarely seen binaries running, and who owns those systems?
  • Are there legacy or abandoned executables still installed that should have been removed?
  • After a patch rollout, did any host keep older, vulnerable binaries around?
  • Did a new software deployment introduce unexpected helper tools, updaters, or sidecar binaries?
  • Are there installers or updaters that behave like droppers and need closer review?
  • Are users running portable or shadow IT tools that bypass standard deployment channels?
  • Are there scripts, macros, or interpreters that are being misused as execution vectors?
  • Which systems are running binaries that SOC or IR has flagged as suspicious or unwanted?
  • Can I quickly find and clean up all endpoints that contain a newly identified unwanted file?
  • Are certain business units or locations consistently introducing more unapproved software?
  • Can I see when and where sensitive admin tools or red team frameworks enter the environment?
  • Are there persistent binaries that keep reappearing because of misconfigured software distribution?

COMPLIANCE AND AUDIT TEAMS

When you care about proof, traceability, and data handling, Stairwell helps compliance and audit teams answer questions like:

  • During an incident, which systems had the malicious or unwanted executables, and for how long?
  • After remediation, can we show that those executables are no longer present anywhere?
  • Can we provide a historical record of what executables were present during a specific time window?
  • Are we sending customer data, regulated binaries, or proprietary code to public analysis services?
  • Can we prove that malware samples and executables stay in a private, encrypted environment we control?
  • Do our malware analysis practices align with data residency and sovereignty requirements?
  • Can we demonstrate that we are not relying on crowdsourced systems that expose customer code?
  • Can we show that newly deployed YARA rules or threat intel were actually evaluated against all historical data?
  • Can we prove that a specific threat did not exist in our environment during a defined reporting period?
  • Are we able to provide auditors with "evidence of absence" instead of just "no alerts observed"?
  • Can we demonstrate continuous, not just periodic, monitoring for malicious executables?
  • Are there persistent binaries that keep reappearing because of misconfigured software distribution?
